thereto and adapted to take removablelegs or supports forming a tripodor similarflstand or ratus according to the preceding paragraph in whichthe removable brackets are carried by clamping bands secured to the bodyof the filter so that the bands and rately removed.

The invention also consists in filtering apparatus according to eitherof the two preceding paragraphs in which the unit it combined with apump unit so that the combined filter and pump may be carried on adetachable tripod or stand.

Further features of the inventionwill be apparent from the descriptiongiven hereafter. j

The accompanying drawings illustrate one con-- venient form of apparatusin accordance with the invention. t

In carrying my invention into effect in one convenient manner, I takeany suitable filter unit a to the body of which I bolt two clampingbands be spaced one above the other. Each of these clamping bands mayhave slots formed in it to tak the supporting brackets d to which thetubular or other tripod legs e are attached. The slots b in the band bare formed with parallel undercut side walls visible in Figure 3 whilethe walls of the slots 0' in the band 0 are both undercut and inclinedto present a; dove-tail formation as clearly shown in Figures 1 and 4.

In the particular construction illustrated each slot b in th upperclamping band and which detachable supporting bracket has a rectangularend portion d which slidably engages with the position by gravity hooksg engaging in holes e (Figure '5) drilled therein. The arrangement issuch that the filter complete with supporting tripod can be freely movedabout and when required the legs dismantled by throwing back the holdinghooks g, an the supporting brackets may be withdrawn after releasing thespring. catches f. Atthe lower end of each leg is hinged a foot supportplate h of adequate area so constructed thattit folds up relativelyparallel with the leg when not in use as shown by the dotted lines inFigure 5, but is counterweighted so that when theleg is assembled withthe filter unit the foot plate assumes a relatively horizontal position(as shown by the full lines in Figure 5) and prevents the leg sinkinginto the ground.

When-it is desired that a combined filter and pump unit shall bedetachably supported on a tripod or thelike, I may provide a plate 2'adapted tobe connected across the upper and lower clamping bands, andsuch plate is furnished with bosses i by means of. which a pump k ofconvenient form may be detachably secured to the plate while the latteris also detachably secured to the clamping rings.

If desired, the filter may be provided with interchangeable connectionson inlet and outlet with caps for back flushing. Thus the connectionfrom the pump to the filter inlet can be detached and coupled to thefilter outlet, thus permitting back-wash through the filter from outletto inlet to aid detachment ofnthe filtering medium,

Any suitable frame or box may be provided for taking the components of adismantled unit, also tool box, mixing tin and tin containing filterpowder, water treatment chemicals and testing set. a i

It will be understood that the invention is not to be limited totheforegoing details of construction which are given by way of exampleonly, as I may modify the means fordetachably carrying the filter andpump upon a stand or tripod so that the partsmay be readily dismantledfor transport, depending upon the purposes for which the installation isto be employed.
